Summary
This should fix yarnpkg#1834 where yarn had resolved the host-git-packages without a hash and downloaded them to the cache folder -. The tarball fetcher would then add the hash after the download completed resulting in the linker believing that the Package could be found in the cache folder --.
Test plan
yarn add mulesoft/api-console.git#master would not work. Now works.
